Fast rotating neutron stars with realistic nuclear matter equation of state

F Cipolletta, C Cherubini, S Filippi, JA Rueda, R Ruffini - Physical Review D, 2015 - APS
We construct equilibrium configurations of uniformly rotating neutron stars for selected
relativistic mean-field nuclear matter equations of state (EOS). We compute, in particular, the …

The Quest for New Correlations in the Realm of the Gamma-Ray Burst—Supernova Connection

MG Dainotti, B De Simone, KM Islam… - The Astrophysical …, 2022 - iopscience.iop.org
Gamma-ray bursts (GRBs) are very energetic cosmological transients. Long GRBs are

Early X-ray flares in GRBs

R Ruffini, Y Wang, Y Aimuratov… - The Astrophysical …, 2018 - iopscience.iop.org
We analyze the early X-ray flares in the GRB" flare–plateau–afterglow"(FPA) phase
